If the dialog resource is actually in the DLL, have you included the following in your
ShowDialogFromDll()function:AFX_MANAGE_STATE(AfxGetStaticModuleState());

But when i put AFX_MANAGE_STATE(AfxGetStaticModuleState()) before my dialog showing code it crashes my program. I get an assetion in WINCORE.CPP line: 884. It crashes because my DLL app does not have a main window. Damn :D

Do you have a RichTextCtrl on your Dialog. If so, you must call AfxInitRichEdit() or AfxInitRichEdit2() before calling your function.
I'm not using rich text. It's blank dialog.

call MFC macro AFX_MANAGE_STATE, before calling any of the MFC functions
May all beings be happy and free...

Show your
ShowDialogFromDll()code.

Show the code, how you are invoking the dialog?

First i am using function PlugInProc for exporting PlugIn class. In that class i have a function called ImportFile: BOOL CPlugIn::ImportFile(CString sFile) { AFX_MANAGE_STATE(AfxGetStaticModuleState()); CImpOpts dlg; dlg.DoModal(); return TRUE; } And when i call this class function from my main application it crashes. And i know why but i don't know how to fix it. Windows figures that CImpOpts is a part of my main application and tries to load dialog resource (IDD_IMPOPTS) from my main app, but resource is found in my dll. Once again, i am exporting whole class from my dll using this function: CMy3dsImpApp theApp; CPlugIn plg; // CPlugIn is of type MPlugIn extern "C" MPlugIn* PASCAL EXPORT PlugInProc() { AFX_MANAGE_STATE(AfxGetStaticModuleState()); return &plg; } I can show modeles dialogs, but i need modal dialog (because i need to stop execution of main application code 'till i do specific code in my plugin).

I'm not sure, but problem may be resource handle. Can you try this, Use this code before invoking
ImportFilefunction.HINSTANCE hResInstCurrApp=AfxGetResourceHandle();
HINSTANCE m_hInstResDLL = LoadLibrary("dllHavingDialog.dll"));
if (hInstResDLL )
{
//set resource handle to this dll
AfxSetResourceHandle( hInstResDLL );
//call you function
AfxSetResourceHandle( hResInstCurrApp);//call freelibaray
}
else
{
//failed to load dll.
